2000.3.20 The launch of Astro E X

NASA, NASDA, and MIT worked together and developed Astro E, observation satellite for X radiation was launched. But due to the problem of launch vehicle, the satellite could not enter the designed orbit and fell to the ground.

Scientists hope that Astro E can observe X radiation more carefully and help them to solve the problem in the regard of the origins of chemicals and material change in black hole. But the failure requires another start. This was also the third failed attempt of Japan's launch and it was the loss of anthropology and satellite observation.
